HV Bushings
HV (High Voltage) Bushings are insulated electrical components designed to allow a high-voltage conductor to pass safely through a grounded transformer tank, switchgear enclosure, wall or other barrier while maintaining the required electrical insulation and mechanical support. They are critical components in high-voltage power systems and transformers. IEC 60137 specifies characteristics and tests for insulated bushings used above 1,000 V.
